Windows 10 handles keys differently.  When you upgrade to Windows 10 via Windows Update from Windows 8.1(or win 7 SP-1) registers your computers hardware, and qualifying OS with a Microsoft Product Activation Server. The device is then considered a Windows 10 device.

Subsequently anytime you re-install (or clean install) the installation checks with those servers, finds the unique installation ID and produces the validation

The key is the same for all users.  The important bit is called the activation ID and it is stored on the activation servers in the MS store.

Thank you for Ur prompt answer in this. May i know how can i get different key for all the machines?

Thanks..

The Free Upgrade version of Windows 10 will use the same key for each edition, Pro vs Home. If you want different keys then you would need to purchase individual Windows 10 licenses for each PC.

Hi Ramaiah,

What's your environment? Did you use the volume license key?

If you perform the free upgrade process, it needn't type any product key to activate. Just skip that phase, and it would activate online by itself after upgrade.
